Description

The invention relates to rocket and space technology, and in particular to devices for assembling aircraft (LA) for various purposes and shapes, consisting of several units (compartments, modules).

A known method of assembling stages of a multi-stage aircraft according to the patent of the Russian Federation No. 2007345 "Method of assembling stages of a multi-stage aircraft with sections of a transport-launch container", using an assembly stand consisting of rails, vertical supports with cradles, carts with cradles, a mechanism for moving carts.

The disadvantages of the technical solution is the possibility of docking aircraft units, only located coaxially, as well as the inability to perform tilting - movement in the vertical plane of individual aircraft units.

The closest analogue is the technical solution of the head unit assembly stand device with the launch vehicle adapter, described in the RF patent No. movement of assembly elements along rails (trolley), fixation devices, tilter for verticalization of assembly elements.

The disadvantage of analogue is the low variability of adjustments of the device elements: the impossibility of rotation of the assembly elements around the longitudinal axis, the impossibility of lateral docking of aircraft units.

The technical task of the invention is to create a device for assembling various types of aircraft, characterized by versatility in terms of the possibility of quick reconfiguration for aircraft of various longitudinal and transverse dimensions, additional degrees of freedom of the tilter, the possibility of lateral docking of aircraft units, while rationally reducing the range of parts and assemblies of the device.

The specified technical problem is solved by the fact that in the proposed device for assembling an aircraft, consisting of a tilter equipped with a faceplate, rails, a cart mounted on rollers, a set of supports and fixation devices, the tilter is equipped with an electromechanical drive for turning the faceplate 360 ° around its longitudinal axis , the rail is made of a U-shaped or L-shaped profile with mounting holes on a vertical surface, the bogie frame is made of two separate sections longitudinal to the rail of a U-shaped or L-shaped profile with mounting holes on a vertical surface, with mounted on each section of the bogie a pair of rollers and supports, while the mounting holes of the rail and the frame section are located along the vertical surface in at least two rows, the relative position of the holes on the rail and their geometric characteristics correspond to the holes on the frame section, the parallel rails and the frame sections of the bogie are connected by fasteners of the “rod” type with p thread - nut" or "plate with angle - bolt-nut".

In the diagrams of Fig. 1 shows a general view of the assembly device. In FIG. 2 ... 4 - its constituent parts. Designations accepted:

1 - rail (rail section),

2 - cart,

3 - vertical supports,

4 - connection "plate with angle - bolt-nut",

5 - bogie frame section,

6 - tilter,

7 - tilter faceplate,

8 - mounting holes in the rail,

9 - mounting holes in the trolley frame section,

10 - connection "threaded rod - nut",

11 - rollers for moving the cart,

12 - rotary frame of the tilter,

13 - layout of the aircraft unit on the trolley,

14 - layout of the aircraft unit on the tilter.

The technical solution device is as follows. Tilter, fig. 1, pos. 6, is designed to install an aircraft unit on it (schematically shown in Fig. 1, item 14) and adjust the position of the unit relative to the rail in the vertical plane and relative to the longitudinal axis of the attached aircraft unit on the trolley (schematically shown in Fig. 1, item 13 ). The tilter includes a swivel frame, Fig. 1, pos. 12, to adjust the position of the aircraft assembly in the vertical plane. A faceplate is installed on the frame (Fig. 1, item 7) with the ability to rotate 360° about its longitudinal axis using an electromechanical drive, not shown in the figures. The use of an electromechanical drive is due to its compactness and ease of connection, along with sufficient power and positioning accuracy.

The rails (Fig. 1, item 1) are used to move one or more carts (Fig. 1, item 2) with assembled aircraft units, as well as to place supports under the aircraft units (Fig. 1, item 3).

The trolley contains a frame U-shaped (Fig. 2, item 5) or L-shaped profile (Fig. 3, item 5) for fixing rollers (Fig. 1, item 11), supports (Fig. 1) on it , pos. 3) and serves to move the aircraft unit (schematically shown in Fig. 1, pos. 13) along the rails.

The possibility of flexible reconfiguration of the assembly device for products of different dimensions in width requires the use of simple and versatile devices that allow you to change the distance between the rails, as well as between the sections of the bogie frame. To do this, the rail is made of a U-shaped or L-shaped profile with mounting holes on a vertical surface (Fig. 2, item 8), the trolley frame is made of two separate sections of a U-shaped or L-shaped profile (Fig. 2…3, pos. 5) with mounting holes on a vertical surface (Fig. 2…3, pos. 9), with rollers and supports installed on each section, while the holes of the rail and frame section are located along the surface at least two row. The mutual arrangement of the holes on the rail and their geometric characteristics correspond to the holes on the frame section.

Making holes in two rows allows you to connect parallel rails using "vertical" pairs of simple fasteners of the "threaded rod - nut" type (Fig. 2, item 10), while adjusting the distance between the rails and the rigidity of the connection. In the same way, the connection (Fig. 2, pos. 10) of the bogie frame sections is carried out and the distance between the sections is adjusted.

Lateral docking of aircraft units requires docking of the end part of the rail to the side. Such a connection is provided by the use of a fastener of the type "plate with an angle - a bolt-nut" (Fig. 4, item 4). At the same time, holes are made on the plate and on the corner in the order of arrangement, which fully corresponds to the order of the holes on the vertical part of the rail. The use of such a fastening element with different values of the bend angle makes it possible to ensure the joining of the rails both under the straight line of Fig. 4a and another given angle of FIG. 4b, as well as to increase the length of the rail path of Fig. 4c, fig. 4g when assembling several units of a long aircraft.

A fastener of the "plate with an angle - a bolt-nut" type can also be used to connect parallel sections of the bogie frame to each other, Fig. 3, pos. 4. The mutual identical arrangement (including the vertical and horizontal distance) of the holes on the rail and on the bogie frame, their identical geometric characteristics (hole diameter) make it possible to ensure the use of the fastener as a universal assembly device for both units.

The technical solution makes it possible to increase the manufacturability of the aircraft assembly device by using universal devices and to reduce the cost of manufacturing tooling in pilot and small-scale production of aircraft of various sizes.
